Once you resolve the functioning issues that sometimes surface in diminutive .45 ACP platforms, they're still pretty much larger overall than similar 9mm platforms, and some .40 S&W platforms.
I prefer my CS9 to my CS45, for example.
The CS45 is a very underrated, very reliable 6+1 .45 ACP pistol, however. It's very quietly popular among many LE users and instructors. Not all that easy to find used. TDA design, although it was available in DAO for a while, and TDA models can still be converted to DAO by the factory (or gunsmiths and LE armorers). The newer DAO design has a longer trigger stroke than the previous models that had longer slides, though, since the older models had their hammers staged to a different degree, allowing for a shorter trigger stroke after each cycling of the slide and 'locating' of the hammer by the sear nose.
While the CS45 feels a bit chunky & blocky in the hand while just holding it, it takes on a different character when being fired in many user's/owner's opinions ... and in my perspective. The chunky Hogues enhance controllability and recoil management, and it's surprisingly accurate for a small .45 pistol. Feeding reliability is something for which S&W .45's are generally well known, too.
As far as the TDA trigger ... the DA trigger stroke is typically long and somewhat heavy (short & stout hammer spring in the CS series), but smooth and predictable for those trained in it, and the SA has a very short reset with a decent feel. Shooting more examples of both models than I can remember over the years, I generally find the TDA S&W pistols to offer slightly better triggers than TDA SIGARMS pistols, for example, day in and day out.
S&W's Lifetime Warranty and free shipping (both ways) is pretty user-friendly, too.
My J-frames, CS9 & G26/27 simply slip into most of my jacket pockets (w/pocket holster) more easily than my CS45.
I mean, I'm a revolver lover, always have been, but I also am a practical person. Love for the revolver doesn't get in the way of my sense of practicality.
